'Application md october 248, ,19;27. semaine. 225,354. fl i Mfinvention relates to screens of the type of. door and window screen generally 575g 7 l' commonly' employed in window and door 'Y frames and? has for itsfgeneral objectv the provision of a novel window screen adaptl ed to flies.

. Another object of my invention is to provide a window screen-for the purpose indicated that will be simple inl Construction, eflicien't in operation, and suitable for manufacturing and selling at low cost. 'y f Other objects and advantages of the method, and construction vherein employed will appear more fully inthe hereinafter specification, when taken in connection vwith 'the accompanyingdrawings, in which l l Figure l is a front elevation of my device.

The screen .'lcomprises themesh l0, stiles ll and Vl2,

As anl importantifeature jof my invention f vthe 'fly escape passageway C, having vthe koblique walls 26, 27 fis-1 particularly adapt-v way 1n a manner to attract insects-0n one o ed to admit rays of light, either direct or reflected, from the sun, vto enter the diag' olnal opening 2,- these rays being percep- .tible from the inner side of the screen.

' The mode of operation and Jfunctioning I `of my novelV screen will now'be apparent upon referring tothe' drawings, 1n connec-V tion* with 'f the Vfollowing brief description.

A is is well known, flies and most species of If a room is darkened by lowering of the blindsV 1 .insects are strongly attracted by light.

therein practically alll of ,they flies will be found between the windowv panes 0r screens and the blinds. Also it is a fact of every day observation that flies upon the interior rid a room of insects and particularly .thereimthereby finding their wayinto the vtraeted to entertherein. In `this respect l `igure2 is a vertical section taken'on lineV fer the tunnel `wil-l havea dark-aspect in 'that may be made without departing from The window frame A comprisesl the dripl Letters Patent is:- i' 1. InA a screen of the vkind described, a

way comprising a diagonal.ebend'v in said '90 rect 'their vcourse to -thenpper partftheref of. In the present instance any flies that"v may be upon the mesh lO willfbe attracted by beamsof daylight entering thefopening 27 of the 'Hypassageway 'C and` will enter 60 outer atmosphere. `In this manner, aroom may in great measure ,be rid-'offlies without*` .resorting to kany directmeans to destroy 1 them. It is to be noted that Vfrom theoutside the 'passageway will appearV dark vto insects, which vconsequently Vwill not be at-` the fly l escape is` substantially similar inf theory to a tunnel, whereinrays of light on f the outside are Vstrongly accentuated/to per-* sons-on the inside, vwhile toy an outside beholdwhich objects may scarcely, if at all, be seen.- I have in practice founclthat the vmethod herein described kand illustrated' is very efficient for the purpose indicated. Y

y lWVhile the above l embodiment is a pr'e-V l' ferred one,'I do not desire to be understood as limiting myself to the' precisedetails as so Y set'forth, but wish to availV myself of such changes of constructionV and arrangement thefspirit and scopeof rmy inventionas defined in the appended claims. .y j What l claim, as new and -desire to secure i ssn yframe enclosing a mesh, an oblique passage frame, said diagonal-bend. being adapted to admitrays ofdayl'ight at a pointwhereg'l Vthe diagonal bend joins the oblique passage-5l sidey of said mesh to entersaid passageway, .'95 but not to lure insects on the `outside to reenterrsaid passageway. l i Y 2.
